ELASTIC WEBBING.

This invention relates to elastic webbing,

primarily but not necessarily intended for use in wide 'WfibSfOI themanufacture of corsets, girdlesand the like.

One of the main. objects is to provide a wide elastic web suitable forcorset manufacture and for being cut up into various the exterior of thecorset, a soft inner face.

suitable for the inner surface of the corset, and combining with thesecharactersitics maximum flexibility, strength and porosity to air forpurposes of ventilation.

Another object is to provide an, elastic web having the ornamentalreticulated outer face, and the soft inner face in which the componentparts are strongly bound together, and which can be securely sewedthrough its body to the part to which it'is to be attached. To these andother ends the invention consists in the novel features and combinationsof parts to be hereinafter described 'and claimed. I

In the accompanying drawings:

Fig. 1 is a greatly enlarged somewhat diagrammatic outer face view of aweb constructed in accordance with this invention;

Fig. 2 is an edge view looking from the left of Fig. 1, and I Fig. 3 isan edge view looking from the bottom of Fig. 1. i I

In the practice of my invention, I prefer to use a single layerofcoveredelastic cords forming a part of the warp. These elastic cordsform the longitudinal sides of a multiplicity of retangles or reticules,made up into a large number of identical patterns. In the particularform shown, there are nine reticules ina pattern, and Fig. 1 shows onecomplete pattern unit with an extra elastic Warp cord at one side, andan extra filling pick at one end. y

, Tlhe drawing shows four covered rubber warps, 1, 5, 9 and 1 arrangedin the same plane in a single layer. Between the lefthand pair ofelastic cords (Fig. 1) are illustrated three textile binder warps 2, 3,1, respectively, constituting in this casethe only textile warps betweenthe covered rubber cords 1, 5. Between the cords 5 and 9 similar textilewarps 6, 7, 8, are interposed,

and between the cords 9and 1 textile warps illustrated in Fig. l.

to the pick 13 in theirarrangement.

10, 11. and 12 are located, this particular instance, the reticules areformed byrun ning a pair of filling picks A, B, acrossthe warps at thelower end of the pattern, and

similar pairs of filling picks E, F and I, J,

above the picks A, B, at theproper intervals. The filling pick AA at thetop belongs properly to thepattern next above, as It will be observedthat each reticule is formed at the top/and bottom respectively,bytwoparallel filling picks, which in practicelie close together, thesides of the reticules being formed by the elastic cords. Thesereticules are filled or stuffed by meansof other. filling picks exposedforthe greater part of their lengths on the back or inner surface of theweb, as hereinafter described. Two filling picks C, 1) cross thereticules between the fillers E, B; and the filling picks H, Grand K, L,are similarly arranged with reference to their respective reticules; The.picks A,B, E, F,

The filling.

under all of the textile warps. The pick B on the otherv hand passesunder all ofthe elastic cords and overv all of the textile warps. Thefiller picks E, I are similar to pick A, and the filler picks F, J aresimilar back fillers which present the soft back surface, are locatedfor the main portion of their length at the back ofthe web, and only atrare intervals go up into the Web body to pass over a binder. Preferablythey pass over and are held by textile warps only, being located beneathall of the elastic cords, as shown, but I do not limit myselfin allaspects of the invention to this particular I ternunit. The back fillerpick G is held only The by the warp 7, so as to be caught and held at apoint offset from the holding points of thcpicks G, D, and thcbackfiller pick L is also caught and held by the warp 7.

-T l i e back filler pick K is held by the binder warp 3, and thebaokfiller pick H by the binder warp 11.

For the elastic cords, I preferably use single threads of 34 rubber,covered with two layers of cotton yarn. The rubber threads are coveredwhile under moderate tension and are held in tension by the covering,that when the web is cut these'elastic cords do not draw up and distortthe fabric. "When these elastic cords are removed from a piece of webthey will ')referably beef substantially the same length as the pieceofweb from which they were removed. This obviates the use of much or anysizing inorder to make the web lie fiat, which sizing would have atendency to reduce the softness of the web. It is preferable in a web ofthis character to have a minimum a'ndount of sizing. The binder picksare preferably arranged in pairs, as above stated, although notnecessarily so in all cases. The textile warps, which are all binders,may be conveniently formed of two threads of 26 hard twisted cottonyarn, twisted together to make up a so-called 262 warpyarn. Each binderfilling pick'is preferably formed of two threads 0f19/2 soft twistedyarn, delivered together by the shuttle to constitute one pick, thesethreads being woven substantially parallel to each other. Twistingtogether of these threads may occur to a certain extent as an incidentof manufacture, but the intention is to have them substantiallyparallel. The binder filling picks have sufiicient strength and at thesame time considerable bulk, and the individual binder picks willbepcreferably about three times as bulky'as the respective textilewarps. The back filling picks used for creating the soft back surfaceare, on the other hand, preferably bulkier than the binder fillingpicks. In the particular case illustrated, the picks'C, D etc., whichpass through the centers of the reticules,.are each made up of threethreads of 19/2 soft twisted yarn, these; threads being deliveredtogether by. the shuttle as one pick in a single traverse of the shuttleand woven in substantially parallel relation. Thuspin this instance, theback filling picks C, D, etc. are each about 50% bulkier than therespective binder filling picks A, B, etc., and are approximately fourand one-half times as bulky as the textile war s 2, 3, 4, etc. Due tothis fact and the met 10d of holding the back filling picks in the web,they present a back web surface of a soft velvety character,notwithstanding theuse of the elastic cords and the relatively thin andhard textile warps. Owing tothe fact also that the filling picks C, D,etc, and

also preferably the picks A, B, etc., are each constitutedbysubstantially parallel threads,

the web is given addcd'flexlbility. The arrangement of the back fillingin the centers of the reticules is also such; as to inake the reticulecenters porous, thus providing proper ventilation.

In the operation of forming the web, one of the loom shuttles weaves twopicks of a filling of one character, e. g., binder filling, and thesecond shuttle weaves two picks of another character, "e. g.,back'filling. This sequence isthenrepeated indefinitely. The binderfilling, as above stated, produces cross ribs in the web and also hasash-011g binding effect. The back filling not only provides a soft backon the web buthas, in addition, a certain spacing efiect. The web mayhave a selvagc of any suitable cl'iaracter.

The web of my invention has a warp in which all the threads are strong;The back filling picks should obviously be woven into the web with verylittle. tension so as to increase the softness of the inner face of theweb. Tlnsalso increases the pm-osu y of the central parts of thereticules formed by the elastic cords in combination with the densecross ribs. The cotton. covering of the rubber cord is preferably suchthat the cross section of the'cord is about three tiines'that of therubber inside, which is usually about nd of and inch square. The twistin the individual threads of yarn used in the filling should beconsiderably less thanthat of the twist in the individualthreads of thetextile warps.

While in'the preferred form each pattern unit contains three coveredrubber warp cords, nine binder warp threads, six binder filling picks,and six back filling picks, it will be understood that these numbers,the sizes of the threads, and the arrangement thereof, are susceptibleof considerable variation within the scope of the invention, and variousother changes may be made in" the details without departing from theprinciples of the invention as defined n the claims.
